Title: Improvements in or relating to waveguide transmission systems
Inventor: KHOURY KHALIL IBRAHIM
IPC: H01P1/162
Filed: 1960-04-22
Abstract: 905,689. Waveguides. DECCA Ltd. April 17, 1961 [April 22, 1960], No. 14272/60. Class 40 (8). A waveguide transmission system makes use of a rectangular waveguide 13 in which a plane polarized TE wave is transmitted with its electric field parallel to the longer sides. The dimensions of the longer sides are such that the guide is capable of propagating more than one mode, but mode filters are used to suppress all except TE no  modes. These filters may take the form of resistive films (e.g. of NiCr alloy) or filaments 20, Fig. 4, extending across the guide parallel to the shorter sides. The short dimension of the guide may be such that modes with more than one half-period of the electric vector are evanescent. Preferably, however, this dimension is great enough to allow propagation of the TE 20  mode and this mode is suppressed by means of slots or arrays of slots or holes 21 arranged on the median lines of the shorter sides. These slots communicate with absorbing means 22. It is possible to use a waveguide capable of supporting third or higher order modes, but in this case it is necessary to use additional slots to suppress the modes of odd order. These slots are situated on either side of the median lines of the shorter sides at the nodal points of the TE 03  mode. They communicate with auxiliary waveguides or resonators designed to absorb the unwanted modes. It is stated that the attenuation is proportional to a factor C 1 /a+C 2 /b, where C 1 , C 2  are constants and a, b are the dimensions of the waveguide. By making a, b large enough, the losses are reduced compared with those of a normal rectangular waveguide. Coupling of the enlarged guide 13 to a normal waveguide 12 is effected by means of a linearly tapered rectangular section 14. The waveguide may contain H-plane bends, consisting of a section 35, Fig. 8, of bent waveguide, displaced, with respect to the straight sections 13, towards the centre of curvature of the bend. The resultant shoulders are closed with conductive material. This construction is stated to prevent coupling between the TE 01  and TE 02  modes. The waveguide may be sealed by means of a dielectric seal 40, Fig. 9, which is located in and matched to the waveguide by means of inductive projections 42 which extend across the longer walls.

Title: Process for the manufacture of phosphorylated hydroxy-acids and derivatives thereof
IPC: C07F9/12
Filed: 1957-05-10
Abstract: Phosphorylated hydroxycarboxylic acids or derivatives thereof are prepared by heating a polyphosphoric acid or pyrophosphoric acid with an ester with an alkanol, amide or nitrile of an aliphatic or aromatic hydroxy-carboxylic acid and, if desired, converting the modified carboxyl group in the resulting phosphorylated compound into the free carboxyl group.  Instead of hydroxycarboxylic esters, amides or nitriles, the tautomeric keto derivatives may be used, these reacting in the enol form. Temperatures of 40 DEG  to 140 DEG  C. are mentioned.  A slight excess of the phosphoric acid is preferably used and the cooled reaction product taken up in cold water, neutralised to phenolphthalein (pH 8,5) with an alkaline earth metal hydroxide, precipitated alkaline earth metal phosphates removed, and the phosphorylation product obtained from the residual solution by concentration or alcohol precipitation as its alkaline earth metal salt.  In examples, phosphorylation products are prepared as barium salts from ethyl lactate, methyl pyruvate, b -hydroxypropionitrile and salicylamide, and converted to the barium salts of the phosphorylated free carboxylic acids.

Title: Improvements in writing instruments with retractable writing tips
Inventor: WAGNER ERNEST VERRINDER
IPC: B43K24/08
Filed: 1952-06-12
Abstract: 720,048. Reservoir pens. WAGNER, E. V. Sept. 9, 1953 [June 12, 1952 ; Dec. 24, 1952], Nos. 14811/52 and 32732/52. Class 146 (3). In a ball-point pen or other writing instrument having the writing unit c axially slidable in a tubular barrel a<SP>1</SP>, a<SP>2</SP> and normally with its forward end c<SP>1</SP> retracted within the barrel by a spring d, and a spring-loaded plunger g, projecting axially from the rear end of the barrel and which can be depressed to trip a spring detent f and protrude the writing tip c<SP>1</SP>, the spring detent f is arranged to flex transversely in two directions substantially at right angles. The plunger g trips the detent in one direction, and a thrust piece flexes the detent in the other direction to enable the detent to return to unit-holding position. An open-seamed metal thrust tube e Figs. 1 and 4, can be engaged at the rear end by the detent.f to hold the unit c with the tip c<SP>1</SP> protruded as shown in Fig. 1. If the plunger g is depressed, a groove g4 engages the detent f and flexes it radially to release the tube e, so that when the plunger is released the spring d urges the unit c and tube e rearwardly of the barrel until the detent f drops into a cam recess e<SP>2</SP> in the tube e. In this position the tip c<SP>1</SP> is retracted, and a bent lug e<SP>3</SP> on the end of the tube e bears against one axially-extending radial face a<SP>4</SP> of a quadrantal notch in the barrel part a2. When the plunger g. is again depressed (Fig. 4), the border of the cam recess e<SP>2</SP> bears against and flexes the detent f laterally until it rides out of the recess, across the lug e<SP>3</SP>, and engages over the end of the thrust tube e to hold the tip c<SP>1</SP> protruded. A track recess g<SP>5</SP> in the plunger allows the nose of the detent to move radially inwardly to hook over the end of the tube e. The unit c and thrust tube e could be integral. In the form shown in Fig. 7, the thrust tube is replaced by a flat-faced, channel-section, thrust bar i and the plunger has a flat plate stem j. The root f<SP>2</SP> of the detent f enters an axial slot i<SP>1</SP> in the bar i, and the latter fits into a rectangular bore in the barrel part a<SP>2</SP>. The bar i has a cam recess i2 for engagement by the detent j. The edge and plane surface of the plunger stem serve to trip and hold deflected the nose of the detent, and it is notched at j<SP>1</SP> to allow re-engagement of the detent nose with the end of the thrust bar i. The barrel may be moulded from polystyrene, the cap b is of metal, and the plunger is die-cast in metal or plastic material.
